The primative brain, the cerebellum and the cerebral cortex. #14 The primitive brain is a region about the size of an apricot. It controls basic functions like blood circulation and controls the ‘fight or flight’ responses. The primitive brain takes over when we experience stressful situations whilst the other parts shut down. This explains why we find it difficult to think clearly whilst under stress. #15 The cerebellum is the part of the brain known as the mammalian brain. It processes your emotions and long term memories. #16 The cerebral cortex occupies about 80% of your brain area. It determines language, reasoning and thoughts. #17 In the 1960’s a scientist by the name of Roger Sperry discovered that different activities
